. APPARATUS FOR CONDENSING STEAM AND HEATING FLUIDS.

SPECIFICATION forming part of Letters Patent No. 285,936, dated October 2, 1883.

Application filed February 12, 1883. (No model.)

To all whom it may concern: Be it known that I, EDUARI) THEISEN, of Lindenau, near Leipsic, in the Kingdom of Saxony, German Empire, have invented a certain new and useful Improvement in Appa ratus for Condensing Steam and Heating Fluids; and the following is declared to be a full, clear, and exact description of the same. This invention relates to improvements in apparatus for condensing steam and distilling fluids; also, for preheating and distilling feedwater for steam-boilers; and these improvements consist in devices by which a large bulk of condensed or'distilled water is obtained with the use of a small quantity of coolingfluid. The main advantage of this apparatus is that the cooling-water employed is converted into a product of condensation or distillation by means of the caloric of the steam to be condensed and by means of counter-currents. The apparatus I employfor this purpose consists of two parts, arranged either one above the other or side by side, and constructed of corrugated plates, the waves or corrugations of which plates may have a special form according to the purpose to be accomplished. Instead of such plates, pipes or tubes arranged one above the other may be employed.

In order to show the invention more clearly,

reference is made to the annexed drawings, in

which- Figure 1 shows, by elevation and partial section, a condensing apparatus constructed according to my present invention. Fig. 2 is a cross-section of the same, with a view of the right-hand side wall. Fig. 3 is a crosssection with a view of the left-hand side wall.

In this apparatus the steam to be condensed enters through pipe a into the space or chamber a, formed between two corrugated plates,

and descends by the cooling applied to this space externally, as will hereinafter be described. The steam would accumulate at the bottom of the upper division, A, of the apparatus, as condensed water, the latter, however,

is immediately drawn off through the pipe b into the. lower part, B, of the apparatus, I

in which part the condensed water enters at the bottom at c. I preferably arrange the pipe I) as a standpipe, and prolong the same to such height that the column of water in this tained in the last-named steam.

' pipe forms a counter-weight or nearly a counter-weight to the pressure of steam entering into the apparatus at a. The cooling-water, which is required to condense the steam in the upper part of the apparatus, enters into such part by the pipe 6, and ascends into the two narrow channels on a by the pressure of a pump or other pressure. These two channels on a are formed by the two sets of corrugated plates or partitions of the condensingchamber above mentioned, and by hollow parts projecting from the sides of the apparatus into the waves or corrugations of the corrugated plates. These parts are filled with a non-conducting material, such as ashes, 1X50. The cooling-water, in ascending the narrow channels m n, is converted into steam in the upper part of such channels (near the entrance of the exhaust-steam) by means of the calori 0 con- The steam from the coolingwater is conducted by the pipef, provided with a suitable valve or cock, into the upper part of the lower apparatus, into which it enters at g. 1 a

In order to prevent water and steam together from being discharged by the pipe j, which may be the case if the cooling-water in the top'of the upper apparatus is boiling, I preferably form a dome by means of a standpipe, a, and I place a partition in f to back the water and allow only the steam to enter pipe a. The steam originating from the cooling-water descends through the pipe enters into the upper part of the lower apparatus, and will be condensed by the cooling-water ascending in channels at a of this lower apparatus. The temperature of such water will be some degrees lower than the temperature of the, steam to be condensed. This condensed steam, converted into water, enters the eductioupipe 71, whereas the condensed water, which has acted as cooling-water in ascending through the channels m n of the lower part of the apparatus, is evacuated with a somewhat higher temperature at d, in order to be mixed with the 0011- densed product from h.

All sediments contained in the cooling-water entering at e and deposited on the outer surfaces'of the corrugated plates may be readily removed by opening the walls of the apparatus, which may be easily accomplished by the ICO clamps o. It is obvious that by the. above-dcscribed arrangement and working of the apparatus a distilled product will flow off at d and 71 resulting from the condensation of steam entering into the apparatus, and from the evaporation of the cooling-water used for such condensing process, which water, after having been converted in that process into steam, is thereafter again condensed in the same appa ratus.

The water-gages i and k at both sides of the upper part of the apparatus serve, one for the control of the ascending cooling-water, the other for the control of the water resulting from the condensation of descending steam.

The clamps oconsist of two screw-bolts with nose-shaped heads. Thesebolts are threaded in opposite directions and enter into one nut, also provided at the two ends with thread of opposite direction corresponding to thethread of the respective bolts. By turning this nut in the one or the other direction, the clamps will be tightened or loosened. Fig. 4 shows a modification of the clamps, provided with one nose solid to thebolt and one movable nose adjusted and clamped by the nution the bolt.

If this apparatus is to' be used only for the purposes of condensing steam and heating fluids, I preferably employ the two parts of the apparatus in such manner that the steam enters into the upper part at a and the coolingwater into the lower part at h. The steam cooled down in the upper part enters the pipe I; and descends to the lower part at b, to be discharged as water at 72, while the cooling-water, entering at h, is warmed in the lower part, and, after having entered the upper part at G, will leave this 'part through f and cook f in a heated state.

In working with high-pressure steam the apparatus maybe multiplied in such manner lhat the heat of the steam, as well as theheat oi cooling-water, may, by arranging a series of corrugated plates, one apart from the other in horizontal distance, forming alternately condensing-chambers for descending steam and cooling-chambers for ascending water, be made use of in such a manner that it will only require the continuous addition of a comparatively small amount of fresh cooling-water to work the apparatus with a continuous flow of steam. l

A further modification of the apparatus is shown in Fi 5 in side View, with the side walls in section, and in Fig. 6 in cross-section, with inside View of the right-hand end wall. The apertures for the exit of the cooling-liquid are indicated in dotted lines in Fig. 6, as these apertures are in the left-hand end wall only. The apparatus in this instance, contrary to that shown in Fig. 1 and 2, has one condensing-chamber, C, only. The small channels m n, for the ascending cooling-liquid at both sides of the condensing chamber or channel a, are, however, divided by horizontal partitions m n in the upper part of the apparatus. In

this apparatus the steam to be condensed onand ascends in the channels on a,

ters by pipe a between the two corrugated plates forming the condensing-chambers, and descends, while the cooling-liquid enters at c flowing off in part below the partition-walls 'm a at If. Directly below the partitions m n two apertures are provided in the end walls of the apparatus, and pipes are provided, co1nnn1nicating with the channels on n, and united outside the end wall by the pipe 1-. Above-the partitions m n apertures and pipe are provided in the same manner, and the same are connected together by pipe 8. The pipes s and r are connected and combined by cook or valve 2. Through these pipe-connections one part of the cooling-liquid is conducted into the channels m n above the partitions m n, (the pipe I) being extended above the entrance of pipe s,) the quantity of such liquid passingsinto the upper channels, on a. being regulated by the cock 1;. This part of the cooling-liquid is converted into steam near the entrance of the original steam. The secondary steam created in the upper channels, m a, is conducted to an upper closed vessel, m. The water carried along with such steam will, deposit at the bottom of said vessel :0, and can be drawn off through cock :0, whereas the steam is conducted by a pipe provided with the valve f,

and enters at 9 into the water condensed from the original steam, and, becoming also condensed, flows off with such water as pure dis tilled water at d. paratus is especially adapted for all those industrial establishments in which is required both a vast amount of hot water and a certain amount of distilled water, such as dyeing-works, chemical works, breweries, &c. For this pur- I05 pose the apparatus illustrated in Figs. 5 and 6 is especially adapted, in which the quantity of distilled water to be gained from the water which has served as cooling-liquid for condensing purposes is to be regulated by the I I0 cock 0-.

I claim as my invention' 1. The combination, in a condensing apparatus, of an upper and lower case or vessel, four corrugated sheets in each vessel, connected I I 5 so as to form central steam-spaces, with spaces at each side for water to circulate through, pipes for connecting the steam and water spaces, respectively, of one portion of the condenser with those of the other, a pipe for sup- I20 plying the steam to the upper part of the condenser, a pipe for withdrawing the water of condensation from the lower part of the condenser and water supply pipe at the lower part of the condenser and discharge-pipe at the upper part of the condenser, the spaces between the respective outer corrugated sheets and cases being filled with non-conducting material, substantially as set forth.
